Abstract: The present disclosure provides a quick-release assembly, a connection structure, a photography accessory, and a quick-release kit. The quick-release assembly includes: a mounting base, a top end thereof being defined with a fixing slot, a bottom end thereof being defined with an accommodation slot, a limiting groove being defined in a bottom wall, an opening at one end of the limiting groove being communicated with the accommodation slot, and an opening at the other end of the limiting groove being communicated with the fixing slot; a sliding member slidably accommodated in the accommodation slot; and a resisting member received in the limiting groove. After assembly, one end of the resisting member abuts against the sliding member, and the other end of the resisting member extends out of a bottom wall surface of the fixing slot.

Abstract: A photography kit is provided, which includes a first photography assembly including a first frame and a clamping assembly including two clamping bodies, a mounting seat, and a first locking assembly. The two clamping bodies are rotatably arranged on two opposite sides of the mounting seat. A connecting part is protruded at outside surfaces of the clamping bodies respectively. An end of the connecting part away from the clamping body is connected with a pressing part, which extends towards a rear end of the mounting seat, so that a pressing space is formed between the pressing part and the mounting seat. The first locking assembly is telescopically mounted to the mounting seat, a limiting part of the first locking assembly extends from the front end of the mounting seat, and the limiting part is configured for being inserted into a positioning hole correspondingly defined on the first frame.

Abstract: A rotary connection structure includes a first external connection assembly and a rotation damping structure. The first external connection assembly is for external connection with a first photography device. The rotation damping structure includes a mounting member, a fastening member, and a connecting member. One end of the fastening member extends through the connecting member to fix and connect to the mounting member. The connecting member is rotatable, in a damped manner, about the fastening member. The connecting member is connected to the first external connection assembly. The first external connection assembly can be a clamp assembly. The mounting member is for connection with a second photography device. The second photography device can be a handgrip, and the handgrip is fixedly connected to the mounting member. The rotary connection structure proposed in the present invention realizes rotation of the first photography device and the second photography device.

Abstract: A mounting and dismounting assembly is provided, which includes a first fixing member including a base plate with one end provided with an inserting post with a first clamping part and the other end provided with a first connecting part; and a second fixing member including a bottom shell and at least one slider located in the bottom shell. An end of the bottom shell facing the base plate is provided with a first inserting hole for accommodating the inserting post, and an end of the bottom shell away from the base plate is provided with a second connecting part. The slider is located at a peripheral side of the inserting post and slidably connected with the bottom shell. A second clamping part clamped with the first clamping part, and an elastic piece connected with an inner side wall of the bottom shell are provided.

Abstract: The present disclosure discloses a composite bearing. The composite bearing includes a housing, two locking assemblies, a transmission assembly, and an unlocking assembly. The housing is defined with a mounting hole. The two locking assemblies are rotatably arranged in the mounting hole in sequence, both two locking assemblies are defined with a through hole configured to mount an external shaft. A side wall of the locking assemblies is provided with rolling members located between an inner wall of the mounting hole and the external shaft. The transmission assembly is connected to the two locking assemblies respectively so that the two locking assemblies may clamp the external shaft in the through hole. The unlocking assembly is connected to the two locking assemblies respectively to drive the two locking assemblies to release the external shaft. In the present disclosure makes it convenient for users to quickly adjust the desired shooting angle.
